If a firewall blocks a photo from being sent, how then can you send it.? Is there's a way to get around it?

I sent a white teddy bear photo that I copied from the KFAN Timberwolves sport blog using my yahoo email account. It had the famous Imus phrase on the bears chest which read....." Nappy Headed Ho". I made up a joke letter and sent it to a friend but she didn't get the picture and consequently the humor of the joke, obviously. All she got was the letter and a box with a small x in the corner without any picture included. This of course was the punchline of the tongue-in-cheek long-winded letter I wote telling her how wonderful she is and then I'd hit her at the end with Imus photo and then say: "Gotcha" or "Can't beleive you fell for all that line of bull".Anyway, please let me know if you can think of a way to send it as I told her I'll try to figure something out. She's holding her breath untill she sees the very funny photo(that is in relation to the topic I sent her)to complete the letter. Can't leave her hangin can we?
